' Application filed June 26, 1922. Serial No. 571,009.

To all 'whom it may concern:

Be it lmown that I, ALFRED H. GALIAGHE, th

ysllled in the art to which it appertains to make and use the same.

This invention relates to carpet cushions. On account of the peculiar use to which a carpet cushion is put it must have certain characteristics to make it practical as a commercial article. It must be such that it can be sold at a low price, and, therefore, it

must be capable of being manufactured at a small cost. This means that both the process of manufacture and the materials of which the cushion is made should be inexpensive. Furthermore, the carpet cushion must have sufficient tensile strength so as not to fall to pieces when handled, andit `been found to be unsatisfactory and impractical due to the following objectionable features (1) a lack of tenslle strength soI that when laid, taken up and relaid, as is necessary in cleaning floors and rooms, the

adding falls to pieces; v(2) an absence of Ermness or body which cannot be obtained in ordinary hair felt -unless it is fulled. The fulling process is expensivey and therefore impractical. (3) I-Iair felt as ordinarily made with the customary washing,`

drying and dusting recesses still retains a characteristic anima odor, due mainly to the animal oils and greases. This -Odor is seriously ob'ectionable. It is ordinarily re'- moved byV e expensive process known as scouring, under which the hair is subjected answer the requirenetting or cheese clot Suitable P n vica:

to repeated washings in soap solutions, or in e presence of naphtha or other volatile oils. The ordinary processes of scouring 4hair result -in a (product altogether too high priced to be use in a carpet, cushion and is suitable only *for hairs and wools used in higher priced fabrics such as carpets, blankets and Wearing apparel.

I have discovered that these objectionable characteristic animal odors can be entirely eliminated by intimately associating the hairs with ozone. This is one of the things which makes it possible for me to produce a thoroughly satisfactory carpet cushion made from animal hair.

in the accompanying drawin in which.

Figure 1 is a plan'view with a part of the hair felt removed to expose the reinforcing fabric; and

vF ig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

In the drawing, the hair felt is shown at 1. This may be a loosely felted body of animal hairs such as that of cattle, calf or goat, but preferably it is a loosely felted mixture of cattle hair and hog bristles. l have found that this particular mixture of fibers produces a felt which (bias very eilicient;v

f cushioning properties 'andit will not become compact and hard in use. Such a felt is disclosed in my' prior Patent No. 1,368,920' and consists in 75% more or less of cattle hair and 25%l more or less of hog bristles, which'proportions are referred in the resent invention. The fe t 1 is reinforce by an ,intermediate .layer of fabric 2. This preferably should be a fabric of open weave with high tensile strength,

The fabric imparts the necessary tensile stren h to the felt. The fabric may be 'coate with, an adhesive so that the fibers of the felt will adhere to it. This ensures a suiiciently rm union between the animal hairs and he fabric. This union is further obtained by a certain amount of inter-lacing of the aml mal hairs withv the strands of the fabric produced'by the felting operatiom/ The carpet cushion .may be made by any I have found thata practical tofirst vpre ae the animl hair wa ,drym' gan c'eanin it.` t is thelifozonizegby. timate contact 'ith air of ozone. Fo1low The improved carpet cushion is illustrated such, as burlap,

ing this it is opened by pickering and is then carded and formed into bats.` 'llhe fabric is saturated in a liquid containing adhesive matter Which is soft and sticky, when moist or subjected to heat, but solid when dried or cool, like glue, size or asphalt. yllhe ozonized bats are laid upon the' felting table with the saturated fabric placed between the bats, in such a Way as to leave the fabric approximately in the middle of the bats, although it may be nearer `one surface than the other. rlhe bats of ozonized hairwith the saturated fabric between them are then frelted, as in the ordinary felting' process, resulting in a sheet of felt which has been both stiened and strengthened by the fabric and that has been made suitable for use as a carpet cushion by the ozonization of the hair.

,llt will therefore be seen that lt have proJ duced a satisfactory carpet cushion made from animal hair, which may be manufactured at a small cost, which is entirely free from odor and which has the necessary ten sile strength.

What lt claim is:

l. The method of forming a carpet cushion which consists in coating a fabric with an adhesive, placing layers of animal hair on both sides of the adhesively coated fabric, and thereafter loosely vfelting the same together, whereby the .adhesive penetrates only those portions of the layers which are immediately adjacent the fabric.

'2. rlFhe method of forming a carpet cushion which consists in PcoatingV a fabric with an adhesive placing a mixture of cattle hair and hog bristles on both sides thereof,

and thereafter felting the same together.

3. 'llhe method of forming a carpet cushion which' consists in coating a fabric with an adhesive, placing a layer consisting principally of ozonized cattle hair in contact with one side of the adhesively coated fabric, placing a layer of material in connacaaei tact with the other side of the adhesiyely coated fabric, and thereafter felting the same together.

4. rlhe method of forming a carpet cushion which consists in coating a fabric with an adhesive, placing layers of deodorized animal hairs on both sides of the adhesively coated fabric, and thereafter felting the same together.

5.-'l`he method of forming a carpet cushion which consists in impregnating burlap with an adhesive, placing layers containing cattle hair on both sides of the impregnated vburlap, and thereafter' felting the. same together.

6. A carpet cushion comprising a loosely felted body consisting principally of animal hair, and an intermediate reinforcing sheet of fabricembedded therein.

7. A carpet cushion comprising a loosely felted body consisting principally of deodorized animal hair, and an intermediate re inforcing sheet of fabric embedded therein.

8. A carpet cushion comprising a loosely felted mixture of cattle hair and hog bristles, and an intermediate reinforcing sheet of fabric embedded therein.

, 9. A carpet cushion comprising a loosely felted body consisting principally of cattle hair, and an intermediate reinforcing sheet of' bu'rlapembedded therein.

10. A carpet cushion comprising a felted body consisting principally of cattle hair, and an intermediate reinforcin sheet of fabric embedded therein, the fabric and only that portion of the felted body immediately adjacent the fabric being impregnated with an adhesive.

l1. A carpet cushion comprising a loosely felted'body of ozonized aniinal fibers and an intermediate reinforcing sheet of fabric embedded therein.
